None of six selected cortical time scale orders passed both SEEG and fMRI sign tests in test participants

We tested whether selected regional orders of temporal persistence had support in both human SEEG and fMRI from separate studies. We reused RAM memory task fits and MICA-MICs resting BOLD series. Strict cortical labels retained 1,862 electrical pairs in 122 people. A fixed person split gave 61 discovery and 61 test SEEG people, and 25 discovery and 25 test BOLD people. Only 10 of 561 named region pairs met coverage limits in both splits. Discovery selected three common and three opposite orders. Exact directional binomial tests used test people only. Holm correction covered all 12 tests. No region pair passed in both modalities. Three BOLD tests passed; no SEEG test passed. The selected electrical tests had only 14 to 26 people. At a conservative local level, power for a true directional probability of 0.7 was 4.7 to 22.9 percent. Several measured differences also depended on grid edges or estimator choice. The result does not establish absence of a shared neural order. The package provides the failed transfer test, code, source data and receipts, all predictions and controls, three figures, and exact repeat checks. The split is internal validation in reused cohorts, not an external replication.
